| abstract | (57) Abstract: To perform a re-melting process on a surface portion 10b of each inter-valve portion 10a of a cylinder head 10 so that a local process can be performed by a simple method, and , Ensure that quality is also obtained. A tip portion of an upper electrode is connected to a cylinder head. In a state in which the upper electrode 1 and the cylinder head 10 are energized between the upper electrode 1 and the cylinder head 10 in a state where the upper electrode 1 and the cylinder head 10 are energized, the resistance between the upper electrode 1 itself and the cylinder head 10 is maintained. By locally heating the surface portion 10b of the inter-valve portion 10a above its melting point due to both the contact resistance heat generation at the interface and the remelting of only the surface portion 10a without transferring heat to other portions. Perform processing. In addition, the upper electrode 1 is connected to the inter-valve portion 10a at least until the solidification of the surface portion 10b of the inter-valve portion 10a due to the stop of energization is completed. To be held in contact with. |
